* Renamed treeView.js to folderTreeView.js (more changes on this file forthcoming) -- this will soon be specifically for folders.
* Added itemTreeView.js, with new Scholar.ItemTreeView class -- specifically for items.
* The items list now supports 3 additional columns: rights, date added, and date modified.
* For now, selecting an item loads the "I'm Feeling Lucky" result of a Google search on the item title.
Added update.rdf for auto-update mechanism (which will get moved out of the extension root by the build system but should stay with a particular tree)
Assigned a new GUID to extension
*** Important: The extension GUID has changed, so you should rename the scholar@chnm text file in your Firefox profile exensions directory to our new GUID "{e007c81c-eb2a-4e1d-b381-d25a45cd11ed}" and restart Firefox ***
More details coming on Basecamp: http://chnm.grouphub.com/W161222
*** Important note: after checking out this code, be sure to delete the compreg.dat and xpti.dat files in your FF profile directory or else the extension will not load. They'll be regenerated when you start FF again, and you won't have to do it again unless we add interfaces or other components. Once I set up the XPI packaging system, this step won't be necessary. ***
- Localization properties are now loaded directly via nsIStringBundleService and available via Scholar.getString(name) -- removed stringbundle from XUL
- Updated status line in bottom right to reflect whether Scholar is loaded correctly or not (temporary, obviously)
Scholar.Folder.erase() -- deletes a folder and all descendent folders and items
Scholar.Folder._getDescendents() - returns an array of descendent folders and items (rows of 'id' and 'isFolder') ("private" for now--could be useful as public later)
Scholar.Folders.unload() - clear folder from internal cache (used by Scholar.Folder.erase())
DB transactions are now automatically nested if beginTransaction() is called when one is already in progress -- the queries aren't committed until the outermost commitTransaction() is called, which is handy for calling methods with their own transactions inside others when the entire process should be a transaction (e.g. Folder.erase() calling Item.erase() for the folder's descendents). Rollbacks are a little trickier -- currently, a rollback in a nested transaction flags the entire transaction for rollback when the outermost commit is reached, which for our purposes will probably be fine.
ScholarLocalizedStrings moved out of sidebar.js and into Scholar.LocalizedStrings
Rudimentary creator adding/editing. lots of things to work on, because it doesn't work.
Added Scholar.CreatorTypes with methods getTypes() (multi-dim array with 'id' and 'name') and getTypeName(creatorTypeID)
Fixed bug in Scholar.Creators.purge() causing SQL error when deleting a non-existent creator
Fixed incorrect field order for itemCreators INSERT queries in save()
Changed setCreator() to take empty creator names (causing DELETE in itemCreators but without shifting up creators below it (or down and above, depending on your perspective) like removeCreators())
The selection no longer lost or moved on folder opening/closing.
The erase functionality works, on Mac (Windows) use the delete (backspace) or forward delete (delete) keys.
unfortunately there are sometimes exceptions so I am not calling erase() on each item until we figure out what the problem is.
view._deleteItem() and view._insertItem() are now view._hideItem() and view._showItem() to better reflect functionality.
Scholar.ItemTypes.getTypes() -- returns associative array of all itemTypes, with 'id' and 'name'
Scholar.ItemTypes.getTypeName(itemTypeID) -- returns pre-l10n type name (e.g. 'book', 'journalArticle')
Removed getLevel()
Updated Object.setPosition() to handle setting the position of new objects without committing, so it can be used within save(). May or may not actually work--my money's on no.
Added Folder.isEmpty()
No Folder.setPosition() yet, but, then, no editing or saving of folders at all--coming soon
Added getLevel() functions to Scholar.Object and Scholar.Folder -- save() and setPosition() not yet updated
Updated sample data to include levels
Added orderIndex (from treeOrder table, now) back into Scholar.Object data
New Scholar.Objects method for treeView: getTreeRows() -- returns mixed array of all Folder and Object objects in the proper order, type testable with instanceof (e.g. if (obj instanceof Scholar.Folder))
Scholar.Objects.get() and getAll() return arrays hashed by objectID again, since they're no longer used directly by treeView
Scholar.Objects.get() now returns the object directly if only one argument and scalar (i.e. one id)
Updated schema and sample data to handle folder ordering
Added include.js for use in non-browser.xul windows to bring in the SCHOLAR_CONFIG and Scholar objects
Adjusted sidebar to use shared object
Added test line (displayable by clicking "Hello, World" before and after sidebar load to demonstrate cross-window access
I also started implementing some of the localization. There is a lot to do still, and I am still learning a lot of the Firefox extension technologies (XUL, adv. Javascript, etc.) but things are going great.
Fixed object retrieval queries to use orderIndex is 0 rather than 1, since that's the default now
Scholar_Objects.getAll() now uses loaded.push() rather than loaded[objectID], since _for (objectID in objects)_ isn't an option with treeview
Scholar_Object.getField() now returns an empty string rather than false for empty values
Added some new core functions:
- Scholar.varDump(), after PHP's var_dump()
- Scholar.flattenArguments(), to flatten mixed array/literal argument lists into a single array
- Scholar.join() -- a version of join() that operates externally, for use on, for example, the arguments object (safer than extending Object)
- Scholar.Hash, a slightly smarter associative array -- not perfect, but brings a proper length property and a few convenience methods (and allows for other additions) -- should probably be limited to places where the length property or other additional additions are needed, since its use is a little non-standard (e.g. you have to remember to do _for (i in arr.items)_ rather than just _for (i in arr)_, to use set(), etc.)
Moved schema file out of chrome and removed XML tags, since it will no longer be accessed by XMLHTTP
Changed schema updater to use XPCOM components rather than XMLHTTP
Converted DB class to a singleton named Scholar_DB
Scholar_DB.query() now returns associative array similar to mysql_fetch_assoc() for SELECT statements rather than a mozIStorageStatementWrapper -- the mozStorage executeDataSet() function doesn't work yet, so we do it this way
Added DB functions:
- beginTransaction(), commitTransaction(), rollbackTransaction()
- columnQuery() -- one column, multiple rows, returned as array indexed by row
- getColumns() and getColumnHash
DB query functions can now handle bind parameters passed as an array of object literals: e.g. [{'int':2},{'string':'foobar'}]
valueQuery() now returns an int for COUNT(*) queries, so the result can be tested without a "0" being true
Changed _initializeSchema to drop existing tables before creating new ones, hacked with try/catch until DROP TABLE IF EXISTS works with the mozStorage extension (it's already in the latest SQLite release)
Added DB_REBUILD config flag to manually trigger schema regeneration
Added debug logging at level 5 for all SQL queries
Updated sample data
